IMPROVEMENT IN SPONGE-HOLDERS FOR ELECTRO-MEDICAL APPARATUS.

Specification forming art of Letters Patent N0. 116,197, dated June 20,1871.

T0 all whom it mag; concern:

Be it known that I, Dr. JEROME KIDDER, of the city, connty, and State of New York, have invented a new and Improved Sponge Holder for Eleetro-Medioal Purposes and I do hereby deelare that the following is a full, elear, and exaot deseription thereof, referen oe being l1ad to the accompanying drawing forming paart of this speoifioation.

'lhis invention eonsists in a novel eonstruction of a holder for holding sponge or other absorbent material suitable for forming the moist pole of an eleetrical apparatus, whereby the said material is securely held, and.the handle, whiol1 is 'usually made of wood, is protected f1om any moisture that may be expressed froxn the sponge, and is thereby prevented from becorning impaired, and wl1ereloy faoility is afforded for' packing in a small space in the ease of a portable eleotrieal apparatus.

In the aooompanying drawing, Figure 1 is an outside view of mynnproved sponge-holder, and Fig. 2 is a central longitudinal section ot the sanne.-

Si1nilar letters of referenee indieate oorresponding parts in both figures.

Als the handle ofthe holder, whichis usually made 0f hard wood varnished on it-s exterior, and may be of any suitable shape. Extending longitudh1ally through the center of this handle is a 1netal oondueting-rod, B, one end of whioh is sorew-threaded for the attaohment of the cnp O of the binding-sorew G, by which the sponge-holder is conneeted with the terminal wire of the battery or other eleetrioal apparatns. Near the other end of the said rod B is a boss, b, whieh is provided with aradialtappecl hole for the reception of a screw, e, loy whioh the rod is rigidly seoured Within the handle. Tl1e end of the rod beyond this boss bis of larger diameter than the body of the rod, and has a sorew-thread, b, formed on it for the attachment of the clamp. The cup O of the binding-sorew 0 has formed on its inner end a serew-threaded soeket, by which it is secnred to the rod B. The clamp consists of a flat plate o1 head, D, of 1netal, having fonned on its inner faee a serew-threaded sooket, a, whioh is sorewed 011 the end of the rod B, and a 10056 plate, E, of metal, of concavo-convex forma, having a eentral hole to fit the exterior of the sooket, and arranged With its eoneave side toward the plate D. F represents a pieoe- 0f sponge, showing the manner of seouring it in the ela1np.

To=seeure the sponge witln'n the clamp the plate D is unserewed fron1 the rod B and a Portion of the sponge is inserted between it and the plate E; the plate D is then screwed upon the rod B and made to clamp'the sponge The spongeholder elamping-plates l) and E may be readily nnscrewed, and so detached fro1n the rod at I), for greater eonvenienoe of paoking in a small spaee.

What I elaim as my invention, and desire to secure by Letters Patent, is

The sponge-holder, eomposed of an insnlating handle, A, oentral conduetlng-rod B, and clamping-plates D and E, the whole oombined substantially as and for the pnrpose herein set forth.

DR. JEROME KIDDER.
